Hello Foamers,

I hope there is someone out there who can help me with the mesh setup for the engineTopoChangerMesh class verticalValves. I think I defined all the necessary boundary patches in the engineGeometry dictionary. However, the motion solver such as moveDyMEngineMesh (foam extend 4.0) gets stuck when the layer addtion/removal mesh modifiers are added:

Adding a layer addition/removal mesh modifier to the poppet of the valve 1
"valvePoppetLayer1"
1
Adding a layer addition/removal mesh modifier to the bottom of the valve 1
"valveBottomLayer1"
2
Adding a layer addition/removal mesh modifier to the piston-valve 1


--> FOAM FATAL ERROR: 
Face extrusion zone contains no faces.  Please check your mesh definition.

    From function void Foam::layerAdditionRemoval::checkDefinition()
    in file polyMeshModifiers/layerAdditionRemoval/layerAdditionRemoval.C at line 123.

FOAM aborting

Does anybody know what is meant with "piston-valve"? I already went through the source and header files of verticalValves, but couldn´t figure it out. Any help would be much appreciated!

Thanks
